Today's Metro had an article on Jaime O'Connor of Halifax, Yorkshire, who has invented (and is selling) an oven shield to prevent the doors from being splattered by cooking foods.
The shield is easy to fit on the door, using suction pads, and she says that users will save a fortune on oven cleaners. She thought it up when husband Dale, who runs an Aga oven servicing business, told her that his customers wanted to know how they could keep the oven doors clean.
She first invented a shield for Agas but then made one suitable for other ovens. They are made in Britain, and are available in several retailers and on their own Oven Door Shield website.
Jaime works full-time in her husband's business and also has to cope with a five-year old and a two-year old. She is quoted in the story as saying "I want to show other mums it is possible to invent your own products and get them out there."
The World patent application for the invention was published in June 2011 as Oven door shield. Both Jaime and Dale are listed as inventors.
In searching for the patent, I noticed that the free Espacenet database did not recognise O'Connor as a valid search term. There were lots of hits for Oconnor, though not for this invention, which could only be found by asking for Connor as the search term. It could easily be thought that there was no patent specification for the concept.
